I am considering purchasing this Catalina 30 std mast but am concerned the surveyor has found the mast has caused a slight depression in the top of the cabin around the base of the mast immediately around the base approximately 1/2 inch away and maybe 3/8" deep. There is absolutely no indication from below and no apparent deflection in the rest of the cabin. There is a wooden column directly below the mast in the corner of the bulkhead of the head which I believe provides support to the mast.1. I am concerned about resale later even if the condition does not worsen.2. I am concerned it may worsen and fail.3. If item 1 or 2 are a concern what are my options and likely costs.
